aarch64: Fix UB in the compiler [PR100200]
The following patch fixes UBs in the compiler when negativing
a CONST_INT containing HOST_WIDE_INT_MIN. I've changed the spots where
there wasn't an obvious earlier condition check or predicate that
would fail for such CONST_INTs.

* config/aarch64/predicates.md (aarch64_sub_immediate,
aarch64_plus_immediate): Use -UINTVAL instead of -INTVAL.
* config/aarch64/aarch64.md (casesi, rotl<mode>3): Likewise.
* config/aarch64/aarch64.c (aarch64_print_operand,
aarch64_split_atomic_op, aarch64_expand_subvti): Likewise.
